Calculation of mining machine output
behind the scenes, the entire bitcoin network shares a public ledger called "blockchain.". This general ledger contains every transaction processed, so that the user's computer can verify the validity of each transaction. The authenticity of each transaction is protected by the electronic signature corresponding to the sending address, which enables users to have complete control over the bitcoin transferred out from their own bitcoin address. In addition, anyone can use the computing power of specialized hardware to process transactions and get a bitcoin reward for it. This service is often referred to as "mining."
bitcoin mining has gone through three stages of development. When bitcoin was just born, the price of bitcoin was very low. People just took bitcoin as a game and used their ordinary computers to mine. However, in 2012, with the rise of bitcoin price, people found that the mining speed of graphics cards was fast, so, People began to buy a large number of graphics cards and assemble them for mining, commonly known as "burning graphics cards"; The third stage is the well-known ASIC miner mining. Since Avalon proced the world's first ASIC bitcoin miner, bitcoin mining has been completely subverted, and mining has become a special professional thing.
180 coins
invest 200 coins, 230 coins can be settled in a round of two months, 1380-1200 = 180 coins can be settled in six rounds of a year, and 200 coins can be g in 52.5 days to rent a miner
you can rent one in 44.5 days for the second one, 29 days for the third one, 21 days for the fourth one, 13.5 days for the fifth one, 5.5 days for the sixth one, and you can pay 200 yuan for two for the seventh one
extended data
using time superposition 153.5 days to earn 200 coins, two medium-sized mining machines run in parallel, the next 26.5 days can settle 200 coins, three medium-sized mining machines run in parallel. In the next 17.5 days, 200 yuan can be settled, and in 8.5 days, six small mines and eight minicomputers can be fully loaded, with a total of 208 days
for the remaining five months, the net income will be 126.8 yuan according to three rounds of calculation (126.8 yuan for four small mines and eight minicomputers) × 3 = 380.4 coins
mining machinery seed 936 + 380.4 = 1316.4 coins, a year later, the most conservative estimate of the value of a coin is 700 one coin
700 × 1316.4＝921480
The output of 28m Leyte coin miner is as follows:
the power consumption of different Leyte coin miners is different, which cannot be calculated accurately
The monthly output is about 1.299 leytes, as follows:
when building bitcoin, Nakamoto wants bitcoin to be a decentralized currency, not only for use and trading, but also for mining. But it backfired. With the increasing value of cryptocurrency such as bitcoin, mining has become an instry. The competition is more and more fierce, and the pursuit of mining computing power is higher and higher. Therefore, from ordinary computer mining, ASIC mining machine and GPU mining machine have evolved
the algorithm of ASIC mining machine is almost sha256, while the algorithm of GPU mining is different. For example, the algorithm of BTG is equihash, and the algorithm of BCD is optimized x13. Although it is not absolute, it can be simply considered that the currency of sha256 algorithm is generally mined by ASIC mining machine. Other algorithms are basically using GPU miner. There are also exceptions. Scrypt's Leyte coin used to be mined by GPU miner, but later scrypt's algorithm was also conquered by ASIC chips, such as ant miner L3 +, which is the ASIC miner used to dig Leyte coin
ASIC miner refers to the miner that uses ASIC chip as the core of computing power. ASIC is the abbreviation of application specific integrated circuit, which is a kind of electronic circuit (chip) specially designed for a specific purpose. Some mining machinery factories have designed ASIC chips specially for computing the sha256 algorithm of bitcoin, and the mining machinery using them is ASIC mining machinery. Because ASIC chip is only built for specific computing, its efficiency can be much higher than that of CPU. For example, the current mainstream ant miner S9 is ASIC miner, which uses 189 ASIC chips, the computing power reaches 13.5th/s, and the power consumption is only 1350W. As a comparison, the computing power of gtx1080ti, the flagship computer graphics card, will not exceed 60mh / s even if it is optimized well. The difference is tens of thousands of times
GPU miner refers to the miner that uses GPU graphics card as the core of computing power. Cryptocurrencies such as Ethereum, bitcoin and diamond use graphics algorithms, so the speed of computing with graphics card will be the highest. Compared with ASIC miner, GPU miner is more well-known, because it is a computer with enhanced graphics card configurationthe purpose of GPU miner is to make money, so we should pursue the power consumption ratio and maximum profit, so we should pay attention to the cost performance. Generally, the medium and high-end positioning graphics cards, such as AMD rx560 and rx570, have high power consumption ratio, which is a good choice for GPU miner. While flagship cards such as gtx1080ti and AMD vega64 have the strongest single card performance, they are not cost-effective in terms of price and power consumption
in addition, the ASIC miner also has some exotic procts, such as the USB miner of burning cat, which is slightly larger than the U disk, and the power consumption is only 2.25w, which is the smallest bitcoin miner at present
